An Oxford University employee alleged to have murdered a hair stylist has reportedly been placed on suicide watch after handing himself in to police.
Somerville College senior treasury assistant Andrew Warren, 56, and US Professor Wyndham Lathem, 42, gave themselves up on Friday after spending more than a week on the run.
They triggered a nationwide manhunt after allegedly stabbing Trenton Cornell-Duranleau, 26, multiple times in Lathem's apartment in Chicago on July 27.
Warren is expected to be charged with first degree murder after handing himself in to police in California.
The Sunday Times newspaper quoted a source close to the investigation as saying: “We are certainly concerned about their mental state.”
Chicago Police said officers were relieved to hear of the peaceful surrenders after fears grew when Lathem had sent a worrying video to family and friends apologising for his role in the murder.
Force spokesman Anthony Guglielmi said: "Once we got word that Dr Lathem had sent that video to friends and family we began getting concerned that perhaps he would harm himself or this could end up more tragically for both of them, so we are relieved that both of them are safe."
A broken blade was recovered and officers have CCTV footage tying the men to the 10th floor apartment, he said.
Warren, who says on Facebook he lives in Swindon, and Lathem, a microbiology professor at Northwestern University, now face extradition hearings to determine whether they can be sent to Chicago for questioning.
